Nintendo Wii Sensor Bar Demystified After a little detective work done by my bros, I explain exactly what the Wii's "sensor" bar is and why you don't necessarily need one. Tags: nintendo wii sensor bar infra red ir wiimote remote tech hacks |

HHO Hydrogen fuel cell - O2 sensor voltage adder This is a very simple unit designed NOT to replace the O2 sensor signal but to simply add variable voltage to it, thereby causing the ECU to lean out your mix and allow the HHO to be more effective. I have been building an EFIE from plans on better-mileage.com(sp) but I started thinking about it and realized maybe we're making this a little more complicated than it has to be. Elaborate circuits do work (I've been building circuits myself for many years) but there is a simpler way to accomplish the same thing AND easier for a typical person to make. Not everyone is comfortable with breaking out the soldering iron and soldering components onto a circuitboard or setting up components on a protoboard to build something elaborate. I wanted to build something that anyone could make, without having to go to that kind of trouble. What you see in this video is a unit that doesn't take the place of the O2 sensor. Instead, it adds extra variable voltage to the already existing O2 (lambda) voltage. The voltage fluctations the ECU expects to see from the O2 sensor are still there, so you don't get the danger of the ECU thinking something is wrong and putting itself into open-loop mode (which causes it to ignore the O2 sensor, negating any gains you were trying to make). This unit allows you to vary the amount of voltage you are adding, but you don't need very much. Normal operating voltage from the O2 sensor runs around 0.45 volts (450 millivolts) but fluctuates about every second or so (the ECU watches for this as a diagnostic). We want to add just a little bit of extra voltage, about another 0.4 volts (400 millivolts) or so to make the ECU believe we are running rich, causing it to lean out the mix and pump less gasoline to the engine. I am using a penlight battery for my potential in this unit but once testing is completed, I'll remove the battery and use stepped-down voltage from the vehicle's 12-volt system to supply power for my potential (eliminating the need for a battery that will need to be replaced periodically) and provide power for a small LED digital voltage meter on the front of the box so that lambda-v voltage can be monitored. The 10k variometer allows you to adjust the trim of your potential's voltage, within a 10k ohm window so that you have control over how much voltage you are adding to the lambda-v. You will never need the full width of this "window" because we don't need to add much additional voltage. I may add resistors to the pot to strictly limit just how much you CAN add and may add a rectifier (diode) to the sensor wire but neither is planned unless I find they are absolutely necessary.

Using two candles as a Wii Sensor Bar replacement Quick note: Yes, this is the ORIGINAL Sensor Bar candle video. After this was posted, many others followed suit, including Joystiq.com. IGN.com even made several references to it in their articles an blogs, and someone referenced it in Wikipedia. Many have heard that the Wii's Sensor Bar does not really sense anything at all but that the remote does all the detection sort of like a monochrome digital camera. What many do not realize is that the Sensor Bar is just two sets of IR LEDs that emit just enough light to be detected by the remote for triangulation. Knowing this, I decided to do an experiment. I turned out all the lights in my living room and lit two candles about three feet apart beneath my projector screen, seeing as they emit several wavelengths of light, both visible and beyond. Surprisingly it worked atleast as well as Sensor Bar when directly in front of the screen (but worse far to the left or right) because of the combination of increased IR light output and increased distance. Any two IR sources will potentially work in this manner (including two TV/DVD remotes with any buttons held). The video was recorded on a Cingular 8125 set to "cool" (bluescale) to capture enough light. I wish I could've used a higher-quality capture method, but the low light made it difficult. At the beginning of the video, I hold up the pack-in sensor bar to show that it is not plugged into the Wii (since it's tough to tell in the very low light of the room). I then grab the Wii Remote and navigate the menus to pull up Wii Sports. http://hullbreachonline.com http://wiioperasdk.com Tags: wii sensor bar two candles leds ir infrared light emitting diode sports nintendo wiimote remote pointer video game entertainment news |
